Cosmological Simulations of Stellar Halos with Gaia Sausage–Enceladus Analogs: Two Sausages, One Bun?

The Astrophysical Journal
Observations of the Milky Way’s stellar halo find that it is predominantly comprised of a radially biased population of stars, dubbed the Gaia Sausage–Enceladus, or GSE.

Dynamical Origins of Azimuthal Metallicity Variations in the Galactic Disk: Insights from Kinematic Ridges with Gaia

The Astrophysical Journal
Kinematic and spectroscopic studies in the past few years have revealed coherent azimuthal metallicity variations across the disk of the Milky Way (MW) that may be the result of dynamical process associated with nonaxisymmetric features of the Galaxy. At

Tracing Back a Second-generation Star Stripped from Terzan 5 by the Galactic Bar

The Astrophysical Journal Letters
The Galactic bulge hosts the Milky Way’s oldest stars, possibly coming from disrupted globular clusters (GCs) or the bulge’s primordial building blocks, making these stars witnesses to the Galaxy’s early chemical enrichment.

Where are the Population III Star Relics in the Simulated Milky Way Analogs?

The Astrophysical Journal
Using six Milky Way analogs with two different numerical resolutions from the Auriga simulation, we investigate the total mass, spatial distribution, and kinematics of the Population III (Pop III) star relics in the Milky Way analogs at z = 0.

RR Lyrae Stars Belonging to the Candidate Globular Cluster Patchick 99

The Astrophysical Journal Letters
Patchick 99 is a candidate globular cluster located in the direction of the Galactic bulge, with a proper motion almost identical to the field and extreme field star contamination. A recent analysis suggests it is a low-luminosity globular cluster with a
